Patent GB-716700-A (GB)
Title: A new and improved analgesic and process for its production
Filed: 1952-11-12
Abstract: The invention comprises a ,a -diphenyl-a -ethoxyacetic acid - b 1 - dimethylaminoethyl ester of the formula <FORM:0716700/IV (b)/1> The compound is prepared by a process in which the hydroxyl group of benzilic acid or its functional derivatives is etherified with ethyl alcohol and its carboxyl group is esterified with dimethyl-aminoethanol, in either order.  The etherification can be effected by transforming the hydroxy group with alkali metals or alkaline earth metals, their alcoholates or amides or with metal organic compounds into the corresponding alcoholates and then reacting these with halogen-substituted etherification components. Alternatively benzilic acid is treated with thionyl chloride or bromide and the resulting diphenyl halogenacetic acid or its carboxyl derivatives are reacted with ethyl alcohol alone or with ethylates, if desired in the presence of acid-binding agents such as carbonates of monovalent or bivalent metals or pyridine.  The esterification of the carboxyl group with dimethyl-aminoethanol may be carried out with or without catalysts and, if desired, the water formed may be removed by azeotropic distillation.  Alternatively a salt of benzilic acid (especially an alkali salt) is reacted with a mineral acid ester of the amino-alcohol and this conversion may be carried out in hydroxyl-free solvents with the addition of anhydrous alkali carbonates.  Transesterification processes may also be employed. During esterification of the carboxyl group the introduction of the nitrogen group may be effected by subsequent exchange of halogen in the esterifying group.  The carboxyl group may also be esterified with amino-ethanol or a reactive ester thereof such as the chloride or sulphonic ester and the primary amino group subsequently methylated.  In examples: (1) diphenyl chloracetic acid is treated with sodium and ethanol to give the ethyl ether of benzilic acid which is subsequently boiled with potassium carbonate and chlorethyl dimethylamine in acetone to give a reaction product which, on extraction with ether and hydrochloric acid successively, yields the hydrochloride of benzilic acid ethyl ether-b -dimethylaminoethyl ester; (2) the potassium salt of benzilic acid is treated with dimethylamino-ethyl chloride to form benzilic acid-b -dimethylaminoethyl ester which is treated with thionyl chloride to give diphenylchloroacetic acid - b 1 - dimethylamino-ethyl ester hydrochloride which is then dissolved in ethanol and refluxed with calcium carbonate, the reaction product being extracted as in the first example.  Specification 641,571 is referred to.

Title: Improvements in and relating to arc welding systems
IPC: B23K9/035
Filed: 1937-10-23
Abstract: 486,724. Uniting by fusion. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 23, 1937, No. 29001. Convention date, Oct. 23, 1936. [Class 83 (iv)] In a method of electric arc welding, a number of electrodes are applied to the work substantially parallel to the line of weld with adjacent ends within arcing distance of each other and arcs are struck between adjacent ends of the electrodes the arcs subsequently engaging the work and dividing into pairs of series connected arcs. A pair of flux coated electrodes 10 may be arranged substantially parallel to the welding line by mounting the bared outer ends in electrically conductive supports 11 connected to respective current terminals 16 and pressed into arcing engagement with the work 12 by spring-pressed plungers 13. The arc is struck between the adjacent ends of the electrodes, whereupon it is transferred to the work and forms two series connected arcs. The flux coating forms a hood over the arcs so as to direct them downwards. For this purpose the coating may be made eccentric to the core or may be made of a portion on the near side which is consumed at a greater rate than the portion on the more remote side. The frame 20 carrying the supports 11 also carries cupreous bars 18 which engage the work on opposite sides of the electrodes and form dams for molten metal. The bars co-operate with a backing member having a central copper part 22 supported between portions 23 grooved at 24. A groove 21 is left between the work and the part 22. Formation of craters at the ends of the work is prevented by strips of metal 25 temporarily attached to each end of the welding line. In carrying out the invention with a polyphase alternating current such as a threephase current, the outer ends of the electrodes may be connected to two terminals of the circuit and the third terminal either to the work or to the mid point of an intermediate electrode in alignment with and twice the length of the other electrodes. In another form the three terminals may be respectively connected to the mid-points of three aligned electrodes of equal length. In a further form, Fig. 8, a series of electrodes 10 may have intermediate electrodes with the connection ends bent and crossed over adjacent electrodes, adjacent electrodes being connected through equal inductances 27 to different phases 26 of the circuit. The crossing of the electrodes prevents the formation of craters at intermediate points of the weld. The bent ends of adjacent electrodes are secured in clamps carried by a spring-pressed yoke and connected to separate supply terminals. In a modification of this form where uniformity of weld is not essential, the connecting ends of the electrodes are not crossed, the fluxed portions being biassed into arcing engagement with the work by pressing the bared ends of adjacent electrodes on an insulating support 40, Fig. 6, mounted on the work by spring plungers 34 connected to the supply terminals 38.
